numpy.ndindex

class numpy.ndindex(*shape)

An N-dimensional iterator object to index arrays.

Given the shape of an array, an ndindex instance iterates over the N-dimensional index of the array. At each iteration a tuple of indices is returned, the last dimension is iterated over first.

Parameters

`*args`ints

The size of each dimension of the array.

Examples

>>> for index in np.ndindex(3, 2, 1):
...     print(index)
(0, 0, 0)
(0, 1, 0)
(1, 0, 0)
(1, 1, 0)
(2, 0, 0)
(2, 1, 0)

Methods

ndincr(self)	Increment the multi-dimensional index by one.
next(self)	Standard iterator method, updates the index and returns the index tuple.
